horrorfan [7]

Answer:

C. But see the answer under C. Apparently C is the accepted answer.

Explanation:

A. Not A.I don't think that's a problem for gulls especially on beaches.

B. Not B.  Their feather do not look like they need much help in keeping their feathers attached when in flight.

C. This is not really the answer, but it is the best answer of these 4. The actual answer is that the bones are porous for better air intake which provides more oxygen and hence they are better able to fly.

D. Not D. Food has nothing to do with the problem. Birds get an adequate amount of food without their wings being porous. See the answer for C.

Earth is the largest terrestrial planet in the solar system. Earth's huge size enables it to exert enough gravitational force to
denpristay [2]

Answer:

Lower gravitational force due to lower mass.

Explanation:

Mars has lower gravitational force than Earth because of its lower size because mass has a direct effect on gravitational force of an object. Earth has mass of 5.972 × 10^24 kg which is 10 times greater than mass of Mars which is 6.4171 x 10^23 kg. So due to earth's more mass, it has more gravitational force than planet Mars which has lower mass than earth.

The term for energy of movement
lara31 [8.8K]

Answer;

-Kinetic energy

Explanation;

The energy associated with motion or movement is called kinetic energy.

-Kinetic and potential energies are found in all objects. If an object is moving, it is said to have kinetic energy (KE). Potential energy is stored energy and the energy of position; gravitational energy.

-An object that has motion - whether it is vertical or horizontal motion - has kinetic energy. Kinetic energy is calculated by the formula 1/2mv², where m is the mass of the object and v is the velocity of the object.

-Therefore, kinetic energy depends upon two variables: the mass (m) of the object and the speed (v) of the object.
